been using a study by princeton economist harvey rosen to back up that romney's plan is paid for by tax cut on middle class but there was pushback from rosen saying he was misrepresented, saying increase in the tax burden on lower and middle income individuals is not required in order to make the overall plan revenue neutral. >> he would be the first to say this is not a monument to one man. >> under backdrop in california today, the president held an official event designating the chavez national monument that may help rally hispanic voters. new politico, george washington university battleground tracking poll of likely voters shows president may have an intensity problem. only 73% support him say they are extremely likely to vote compared to 86% who back romney. >> they know the race has tightened. >> bret: ed henry traveling with the president in california. ed thanks. >>> we are less than a month away from election day. much of the country is already taking part in early voting. we are taking our weekly look at how the electoral college map is shaping up. joining me again today are
